IAMTimeline::GetDefaultTransitionB

The GetDefaultTransitionB method retrieves the default transition. This method is equivalent to IAMTimeline::GetDefaultTransition, but receives a BSTR value, rather than a GUID.

Syntax

  HRESULT GetDefaultTransitionB(
    BSTR *pGuid
);

Parameters

pGuid

[out, retval] Pointer to a variable that receives a BSTR value representing the GUID of the default transition.

Return Value

Returns S_OK if successful. Otherwise, returns E_OUTOFMEMORY or another HRESULT value indicating the cause of the error.

Remarks

The method allocates memory for the string. The application must call SysFreeString to free the memory.
